Setting Method
Setting Current
The current knobs (AL1, AL2) are used to set the current.
The current can be set to 10% to 100% of the maximum setting range.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the current.
The maximum setting range will differ depending on the model and the input terminal.
Example: K8DT-AW3 Using Input Terminals I3-COM
The maximum measuring current will be 200 A AC and the setting range will be 20 to 200 A.
Operating Time
The operating time is set using the operating time knob (T).
The operating time can be set to between 0.1 and 30 s.
If the input current exceeds (drops lower than) the set value, the alarm indicator will start flashing for the set period and then stay lit.
Startup Lock Time
The startup lock time is set using the startup lock time knob (LOCK).
The startup lock time can be set to between 0 and 30 s.
The startup lock time will start when the input current reaches 30% or more of the set value.
Use startup lock time to prevent unwanted operation, e.g., as a result of inrush current.
Note: This function is valid only for overcurrent operation.
Errors are not detected
during this time.
